A fiber optic cross connect system comprising a case defining a tray receiving space and at least one tray slideable in and out of the space between a first closed position, a second intermediate position and a third open or accessible position and a sliding engagement between a sidewall of the case and a side edge of the tray is disclosed. The sliding engagement comprises an elongate link member which is stationary as the tray is moved between the first closed position and the second intermediate position and moves with the tray as the tray is moved between the second intermediate and the third open position and such that the elongate link member does not interfere with fiber optic cables which are interconnecting external devices with devices on the tray. In a particular embodiment the link member is held stationary by a releasable locking mechanism.

A slide rail assembly includes a first rail, a second rail, a mounting member, a third rail, a fourth rail and an engaging member. The mounting member includes a first part, a second part and a third part. The first part and the second part are connected to the third part and respectively extended along different directions. The third rail is connected to the first part of the mounting member, and the third rail is movable relative to the first rail. The fourth rail is connected to the second part of the mounting member, and the second rail is movable relative to the fourth rail. The engaging member is movably mounted to the mounting member. The engaging member is configured to allow the mounting member to be synchronously moved with the second rail along a predetermined direction.

A slide rail assembly includes a first rail, a second rail, a slide-facilitating device, and a working member. The second rail is movably mounted in a channel of, and is displaceable with respect to, the first rail. The slide-facilitating device is movably mounted between the rails and includes an engaging feature. The working member is provided on the first rail and includes a main body portion, an elastic portion for supporting the main body portion, and a predetermined portion connected to the main body portion. The first rail includes a supporting portion for supporting the elastic portion of the working member. The engaging feature is engaged with the predetermined portion of the working member when the slide-facilitating device is at a predetermined position.

A slide rail assembly includes a first rail, a second rail, a slide-facilitating device, and a retaining member. The second rail is movably mounted in a channel of, and is longitudinally displaceable with respect to, the first rail. The slide-facilitating device is movably mounted between the rails and includes an engaging feature. The retaining member is provided on the first rail and includes an elastic portion with a predetermined feature. The first rail includes a limiting feature for preventing deformation of the elastic portion. When the second rail is moved out of the channel after displacement in an opening direction with respect to the first rail, the slide-facilitating device is at a predetermined position, with the engaging feature engaged with the predetermined feature.

A mounting apparatus using a sliding mechanism for easy insertion and removal of insertable units includes a supporting bracket and a sliding mechanism. The sliding mechanism includes an outer rail, a middle rail, an inner rail, a latching unit, and a locking unit. The latching unit includes first and second guiding portions on the inner rail, first and second positioning members slidably mounted to the middle rail, and third and second guiding portions on the outer rail. The locking unit includes a locking member at end of the inner rail and a locking portion on the middle rail to correspond to the locking member.

A fiber optic cross connect system comprising a case defining a tray receiving space and at least one tray slideable in and out of the space between a first closed position, a second intermediate position and a third open or accessible position and a sliding engagment between a sidewall of the case and a side edge of the tray is disclosed. The sliding engagment comprises an elongate link member which is stationary as the tray is moved between the first closed position and the second intermediate position and moves with the tray as the tray is moved between the second intermediate and the third open position and such that the elongate link member does not interfere with fiber optic cables which are interconnecting external devices with devices on the tray. In a particular embodiment the link member is held stationary by a releasable locking mechanism.

A slide rail assembly includes a first rail, a second rail, a blocking member, and an operating member. The rails are displaceable with respect to each other. The blocking member is coupled to the first rail. The operating member can enter a predetermined state with respect to the second rail. When the second rail is at a predetermined position with respect to the first rail, the operating member is in the predetermined state and blocked by the blocking member to prevent the second rail from displacement from the predetermined position in a predetermined direction. When the operating member is not in the predetermined state and hence not blocked by the blocking member, the second rail can be displaced from the predetermined position in the predetermined direction.

An arrangement includes a first drive device for moving a movable furniture part, a second drive device for moving the same movable furniture part, and a synchronization device for synchronizing the two drive devices. The two drive devices can assume different positions during the movement of the movable furniture part. The arrangement also includes a correction device, by which both drive devices can be brought into the same position.

A drawer slide having first and second rails interconnected by a center rail. The center rail includes a spool configured to provide half-speed travel of the center rail relative to the travel of the first rail. The drawer slide is configured for use with a drawer assembly having a drawer and a chassis. The drawer assembly further includes a radius limiter secured to the center rail. The radius limiter travels at half-speed relative to the drawer. The radius limiter also automatically rotates relative to the travel of the drawer. The chassis includes sides including threaded backing plates, and mounting brackets. The mounting brackets include tri-lobed holes for receipt of a reciprocally shaped washer and a fastener for mounting the brackets to the chassis sides.
